We have a heavy duty Tri-ball hitch, works slick, and no nuts to come loose. I have had one incident with a trailer, was pulling a fully loaded 16000# water trailer home from town, and on the highway the tire shot off, every lug broke, all eight, with a 22.5 semi tire on a steel wheel, had to limp it 3/4 mile to a site my parents own. Then we had to go get the 200+ lb tire out of the ditch, luckily, when it shot off, it went into the corn field, then came back and stopped by a field approach. Also lucky we have a loader tractor at that farm, that would've been impossible for my mom and I to load into the pickup.
